Yes.

However, I made my diagnosis with the fact that the PCM isn't communicating with your scan-tool at all.

Not usually. Most PCM'* are in the engine bay.

Hang on a sec though, are you SURE you have an OBD2 system? Your car is a 95. OBD2 wasn't standard until 1996.

Your scanner may be OBD2, but the computer in your car is OBD1.5. Only a couple of scanners out there can read the 1.5 systems. Probably your only option is to find someone that can read them, or take it to the dealer.

This is what I was trying to get at. Thanks Mike.
